Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed October 11,1905. Serial No. 282,222.

To (LZZ whom, it may concern:

Be it known that I, CLARENCE 0. Cor.- LETTE, a citizen of the United States, and a resident of Amsterdam, county of Montgomery, State of New York, have invented new and useful Improvements in Leak-Stoppers, of which the following is a specification.

My invention relates to a means for closing openings in receptacles or other bodies.

The object of the invention is to provide a means for closing holes in receptacles or bodies for containing liquids or gases, especially where the liquids or gases are subject to heat.

It particularly has for its object to provide a means for closing holes in granite ware formed by use or by being punctured.

The invention also consists in providing an elastic body which compresses on a washer around the edge of the hole in the receptacle to be closed.

The invention consists in providing an elastic cap which is adapted to compress a washer by the operation of a screw passing through the opening to be sealed.

The invention also consists in other features set forth in the following specification, claimed in the claims, and illustrated in the drawings.

Referring to the drawings, Figure 1 illustrates a sectional view of one form of my invention. Fig. 2 illustrates a bottom view of the elastic cap. Fig. 3 illustrates another form of my invention. Fig. 4 illustrates a bottom view of the cap. Fig. 5 illustrates my invention when applied to a corner of the receptacle to be sealed. Fig. 6 is a side view of the same. Fig. 7 illustrates my invention when applied to a cylindrical surface, such as a tube. Fig. 8 illustrates a top view of the said device illustrated in Fig. 7. Fig. 9 is an illustration of a modification of the device illustrated in Figs. 5 and 6. Fig. 10 is a side view of the device illustrated in Fig. 9. Fig. 11 is a sectional view of a modified form of my invention. Fig. 12 is a bottom view of the form of the invention illustrated in Fig. 11. Fig. 13 illustrates a sectional View of my invention when applied to a receptacle. All of the figures are magnified views of the device itself.

Referring to Figs. 1 and 2 of the drawings, 1 indicates a cap having a flexible bulging centralportion 2 and a rim 3, extendin around the said elastic central portion. A olt 4 is attached to the top of the cap 1 and extends downward from the elastic portion and in the center thereof. A disk of cork 5 covers one side of the cap 1. The outer edge of the cork is adapted to be compressed by the rim 3 of the cap. A nut 6 is located on the end of the bolt 4 and is adapted to draw the bolt against the side of the receptacle, as illustrated in Fig. 13. The elastic portion 2 of the cap 1 permits of expansion and contraction of a olt 4 through heat and also expansion and contraction of the metallic cap 1 and of any expansion and contraction that may exist in the wall 8 of the receptacle. It also causes the rim to adjust itself to the surface to which it is applied. If there is any roughness or unevenness, it will adapt itself thereto and seal the opening. It, moreover, ermits of the wear or any shrinkage of tie cork which may be due to boiling or otherwise treating the contents of the receptacle which is sealed by my invention.

The invention being especially adapted to the use of cooking-receptacles, particularly graniteware, the same is subject to great changes of heat, and, moreover, comes in contact with a great many kinds of foods and vegetable acids. and odorless does not in any way efl'ect the food. Moreover, in cleaning the receptacle the sealing body is frequently struck by cleaning implements and the edge of the cork is liable to be worn. The elastic portion of the cap, however, keeps the rim of the cap tightly compressed against the edge of the cork disk at all times and prevents any leakage through the opening.

In Figs. 3 and 4 I have shown a modification of the invention. A nut 9 is secured to the central elastic portion 2. The bolt, which is of the same character described in connection with Figs. 1 and 2, is provided with a head 10, broad and flat. It is preferably plano-convex in shape. The bolt is screwed into the nut 9. This then c0mpresses the rim 3 against the edge of the cork disk 5 and seals the same. The flat head of the bolt 10 greatly reduces the amount of protuberance of the bolt beyond the receptacle.

Fig. 5 illustrates the invention illustrated in Figs. 1 and 2, but modified so that it may be used for the purpose of sealing a hole formed in the corner of the receptacle. The cap 1 is provided with the elastic central portion 12, surrounded by a rim 13. The rim 13 is divided into halves. One half of the rim is located at right angles to the other half and is The cork being tasteless bolt 15 is located in the center of the elastic portion 12, as before.

The elastic central portion permits of the adjustment of the device to the walls of the receptacle when the hole is located at different positions relative to the corner formed between the walls of the receptacle. It permits of clamping the walls whether they form an exact right angle or not or whether they form exactly the same angle to each other that the parts of the cap form to each other before it is applied. As soon as the bolt is drawn through the opening the elastic cap begins to compress one of the walls, and upon further drawing in of the bolt by the operation of the nut the other wall of the receptacle is also clamped. This permits of great flexibility in the use of the device. I

Figs. 7 and 8 illustrate the same form of the invention illustrated in Figs. 3 and 4, but modified so as to be applied to a cylindrical body. The cap 1 has an elastic central ortion 16, to which is attached a nut 9. mo

- this nut is screwed the bolt 17, having a large In Figs. 9 and 10 is illustrated a modification of my invention and is to be used where the hole is formed near the corner of the receptacle having right-angular or substantially right-angular walls. The bolt is in this case located at right angles to one part of the rim 13 of the cap 1, and the bolt 19 is inserted in the hole as before, and the cap 1 is clamped against the cork 14.

In Figs. 11 and 12 is illustrated a further modification of my invention. In this form of my invention a male and a female screw are used. The female screw or extended nut 20 is attached to the flexible portion 21 of the cap. It passes down through the cork 5.

The male screw extends from the outside of the receptacle into the female screw, and

when the head presses against the exterior of the receptacle the cap 1 is clamped against the cork, and the cork is compressed around the outside of the hole, and the receptacle is sealed from leakage.

In Fig. 13 is illustrated the application of the device illustrated in Figs. 1 and 2. The cork 5 is placed over the hole 7 which is to be closed, and the cap 1 is placed over the cork 5, and the bolt 4 is inserted through the hole 7. The nut 6 is then screwed onto the bolt, and the same pulls down the cap 1, so that the rim 3 compresses the cork 5 against the wall 8 of the receptacle and tightly seals the opening and prevents the escape or inlet of any liquids or gases contained in the recep tacle.

My invention may be further modified by those skilled in the art without departing from the spirit thereof. v

What I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a sealing device the combination of a flexible cap, a disk of cork and a bolt for causing the cork to be elastically compressed against the walls of the receptacle to be sealed.

2. In a sealing device the combination of a compressible body, a cap having a flexible portion and adapted to compress the said compressible body, a bolt for causing the said cap to compress the said compressible body against the interior surface of a receptacle.

3. In a sealing device the combination of a cap having an elastic central portion, a rim surrounding the said elastic portion, a cork, a bolt adapted to cause the said rim to compress the cork against the interior surface of the receptacle.

4. In a sealing device the combination of a cap having an elastic bulging central portion, a rim surrounding the said central portion, a cork disk adapted to be compressed by the said rim, a bolt adapted to operate on-the said elastic portion to cause the said disk to be elastically compressed against the interior surface of the receptacle.

5. In a sealing device the combination of a right-angular cap having a bulging elastic central portion, a right-angular rim located around the said central portion, a bolt lo cated centrally with respect to the said bulging portion and the parts of the said rim, a cork disk adapted to be compressed by the said cap, means for causing the said disk to be elastically compressed by the said parts of the said rim against the walls of a receptacle located substantially right angles to each other.

In testimony whereof I have signed my name to ti? is specification in the presence of two subscribing witnesses.
